Development of new technological process (including mathematical modeling and numerical simulation of chemical processes and heat and mass transfer processes) in the process and food industry for obtaining biologically valuable components of functional food. Promoting and implementing management of new by-products of the fruit and vegetable industry in Republic of Serbia. This implies the selection of appropriate procedures for the preservation and processing of by-products. Determination of working parameters for the process of dehydration of tropes obtained by squeezing fruits and vegetables, grinding of dehydrated tropes and granulation in order to prolong durability, improve physical and technological properties, as well as use as a carrier of micronutrients or probiotic microorganisms or as a component of composite flour for various purposes.

• Mathematical modeling and optimization of in food science and technology, material science and environmental protection
• Non-linear kinetics modeling
• Quality prediction, according to various quality parameters according to starting materials, pre-treatment techniques, processing methods and the impact of different additives, using mathematical models such as: polynomial models, artificial neural network, support vector machine, boosted trees regression, random forest regression, multivariate adaptive regression splines models, etc.
• Numerical modeling - coupling of Discrete Element Method / Computational Fluid Dynamic for modeling fluid and granular materials transport and mixing in industry (screw conveyor, static mixers, etc.), optimization of process equipment geometry
• Statistics, chemometrics, quantitative structure retention relationship, structural equation modeling, etc…

Application of electrochemical and spectrophotometric methods for determining the total reducing ability and antioxidant activity (polyphenolic grape extracts, complex food samples, by-products of the food industry). Physico-chemical characterization of dehydrated products, flours, powders and granules, determination of their thermal properties and monitoring of stability and durability during standing. Determination of antidiabetic (reduction of glycemic index) prebiotic and anticancer potential, digestibility, etc., dehydrated tropes obtained by squeezing fruits and vegetables. Cooperation with ITNMS, Faculty of Chemistry and Agriculture, University of Belgrade, Institute of Food Technology in Novi Sad, Faculty of Technology in Novi Sad, Institute of Field and Vegetable Crops in Novi Sad and Faculty of Science, University of Novi Sad, Faculty of Agriculture in Zagreb, Croatia and others.

The commercial potential of functional products based on flour from different tropics will be examined within the TTF projects planned for 2022. The possibility of binding heavy metals (bioremediation) to individual tropics and / or biofuel obtained by tropic pyrolysis (cooperation with ITNMS) will be examined.

For almost three decades investigations have been conducted aiming to valorize food industry waste in a sustainable manner towards a “zero waste” economy and wellness.

• Utilization of byproducts of brewing, dairy and fruit and vegetables processing industry
• Development of functional food and dietary supplements
• According to IGPC know-how dietary supplements based on brewing waste, with metabolic effects proved by human trial, have been produced
• Spreading based on whey – technological solution
• Anti grain flour based on fruit and vegetable pomace – patent protected technology
• Functional food based on anti grain flour - patents on pending

Research on the mechanism of selenium nanoparticle formation (SeNPs) in fungal mycelium (green synthesis), cooperation with the Faculty of Biology, the Institute for Multidisciplinary Research, UB and others. Investigation of interactions of fungi from the genus Trichoderma and different plant species (cooperation with Educons University).
